1'0 all whom; it may concern.-

' used or partly used therefrom, to provide for an air-passage to assist the ready flow of liquid from the bottle, to furnish means for preventing interference with the closure of said bottles, to render the action of the closure of view showing the construction of the drainsaid bottles more efficient, and other objects, as are specified herein and pointedout more fully in the claims.

To these ends my invention consists of the.

construction, arrangement, and combination of parts, as herein specified, and illustrated in the drawings in this specification, in

, detail view of the valve-plug used to close the passage-way in the closure of the bottle. Fig. 5 is a view of the bottle with a part broken away at the base, showing a means of closing the end of the air-tube used in connection with the closure. Fig. 6 shows a cross-section of a bottle complete fitted with a modi fied form of my closure. Fig. 7 is a detail shield used in the modified form shown in Fig. 6.

Similar characters of reference denote like and corresponding parts throughout the several views; a l

Referring to the drawings, 1 and l designate bottles to which my closure is fitted. In the bottle 1 a throat or valve-seat is provided by the inward-extending flange 2 at the junction of the neck andbreast of the bottle. The said breast is ground out in conical shape at 3 and is adapted to pe exactly fitted and closed by the conical end of the valve-plug 4, which plug is provided with vertical frets 5 5 5, adapted to rest against the concave surface ofthe inner side of the neck of the bot; tle, butallowing the same to slide loosely therein. A recess 7 in the top of the valveplug furnishes a seat for an elongated spiral coil-spring 6, the upper end of which impinges against the central part of the. dr'ainshield 10. The drain-shield is prefe rably constructed from-glass 'or porcelain and is' provided with drain-holes 11 11, &c.;through which liquid may pass outward and air passinward intothe bottle. Thesaid drain-shield. before setting into the bottle is coated with liquid glass or insoluble cement'and securely cemented into its place inthe neck of the bottle, it being pressed down upon the spring 6 until the said spring is compressed to a ten sion just sufiicient to hold the conical end 4 of the plug in close contact with the throat of the bottle. Thisinsertion and adjustment are made by holding the bottle in the inverted m of the bottle, if preferred When this tube is used, it may be adjusted to such a length that thelower end of the tube Sis closed by contact with the bottle simultaneously with the closure of the throat of the bottle by the plug, as before explained. The closiire, however, is operative without. said tube added, and any extension of the tube down into the body of the bottle will adapt it to serve as an air-inlet to the bottle during the operation of pouring out liquid there- I from.

In the substitute form of theclosure shown in Fig. 2 a member 14 is fitted with the workihg parts of my closure, as described, and the said member 14 is then slid into the plain neck of an ordinary bottle and cemented into place by liquid glass or other suitable cement.

In the modified form shown in Fig. 6 the neck 13" of the bottle is fitted with an annular seat 15,0n which rests a drain-shield comprising two parts, one part or disk 10" designed to rest on the annular shoulder 15 and having a flange 16 extending around the edge thereof, designed to support an addit' nal disk or shield member 10', having rain-holes 17 17, &c., which arestaggered or alternated in circumferential position with the drain-holes 11 through the lower member of the shield'lOQ. By this arrangement of-drain-holes in the'sh-ield the closing valve or plug is rendered difiicult of access by persons intending to tamper with same.

The operation of the device is as follows: The bottle is filled beforemy closure is added. It having been previously ascertained to what height the drain-shield 10 must be located in order togive the proper tension to the spring, the parts of the closure are then put into position and secured. When it is attempted topour out the liquid, the weightof the liquid within the bottle added to the weight of the valve-plug compresses the spring 6, thus allowing the liquid to escape and trickle around the side of the plug be-' tween the frets 5. 5 5, whence it finds its way out through'the drain-holes 11 11, &c., in the shield 10, some of which serve for an inlet of air during the process.

. Having thus described my invention and the operation thereof, what I claim, and desire to secure by Letters Patent, is

1. In a bottle-closu re of the kind described,

the combination with the neck of a bottle having a contracted openingtherein, a plug arranged to close said opening, a perforated shield adapted to be rigidly secured above said plug, a spring arranged to be constrained between said shield and the plug aforesaid, and an air-tube extending through the plug aforesaid into the interior of the bot- .tle, substantially as specified.

2. In a bottle-closure of the kind described, the combination with a neck of a bottle having a contracted opening therein, a plug arranged to close said opening, a perforated shield adapted to be rigidly secured above said plug, a spring arranged to be constrained between said shield and the plug aforesaid,

and an air-tube extending through the said :F. J. DE LAGEY,
